|Full description=Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use; these include command line editing, unlimited size command history, job control, shell functions and aliases, indexed arrays of unlimited size, and integer arithmetic in any base from two to sixty-four. Bash can run most sh scripts without modification.

GNU Bash

https://www.gnu.org/software/bashBash is the shell, or command-line interpreter, of the GNU system. It is compatible with the Bourne Shell, but it also integrates useful features from the Korn Shell and the C Shell and new improvements of its own. It allows command-line editing, unlimited command history, shell functions and aliases, and job control while still allowing most sh scripts to be run without modification.

Documentation

For more information on the features of Bash that are new to this type of shell, see the file `doc/bashref.texi'. There is also a large Unix-style man page. The man page is the definitive description of the shell's features. See also the Bourne-Again SHell manual.

See the file POSIX for a discussion of how the Bash defaults differ from the POSIX spec and a description of the Bash `posix mode'.
